Modular operations center for in-ground swimming pool

A modular prefabricated filter/circulating system for in-ground swimming pools is provided. The swimming pool circulation system which serves to filter and circulate pool water is designed to be prefabricated at the factory and carried to the swimming pool site as a package and installed on the swimming pool wall so that one side wall of the prefabricated package becomes an integral part of the swimming pool wall. The system is provided with a skimmer with streamlined faceplate, main drain, skimmer filter, main drain filter, skimmer throttle valve, quick connect from filter to pump and return, pump, automatic safety pump shutoff, high efficiency pool returns and automatic pool sweep pressure increase mechanism. The system is designed to avoid conventional piping and trenches therefor normally associated with conventional swimming pool filtration systems. The system affords substantial energy saving and is more reliable and safer.
